May I suggest once again that you use the quicksort Routine that I posted Yesterday, using pure REXX? you will see that it is very fast. but: you have to use the non recursive Variant, because Most REXX Implementations will be Limited on the number of call Levels

Now I have to do the allocation of SORTIN, SORTOUT and SYSIN (control cards) then invoke SORT, very cumbersome compared to the simple PIPE command version. > > Al Nims > UFIT > University of Florida > (352) 273-1298 > @Home > > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] > On Behalf Of Elardus Engelbrecht > Sent: Wednesday, June 07, 2017 1:14 PM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: Re: AW: Rexx SORT (was: ...
